An efficient nonlinear multigrid solver for the simulation of rarefied gas cavity flow
Zhicheng Hu, Guanghan Li
We study efficient simulation of steady state for rarefied gas flow, which is modeled by the Boltzmann equation with BGK-type collision term. A nonlinear multigrid solver is propos…

We study the acceleration of steady-state computation for microflow, which is modeled by the high-order moment models derived recently from the steady-state Boltzmann equation with…
A Nonlinear Multigrid Steady-State Solver for Microflow
Zhicheng Hu, Ruo Li
We develop a nonlinear multigrid method to solve the steady state of microflow, which is modeled by the high order moment system derived recently for the steady-state Boltzmann equ…
Numerical investigations of traveling singular sources problems via moving mesh method
Zhicheng Hu, Keiwei Liang
This paper studies the numerical solution of traveling singular sources problems. In such problems, a big challenge is the sources move with different speeds, which are described b…
